Definitions

  • the invention relates to vertical or so-called carousel lathes, in which the workpiece to be machined is arranged on a table or chuck which rotates on a vertical axis.
  • the tool-carrying slide or slides are mounted on a horizontal guide or cross beam which in turn can be raised and lowered.
  • the invention proposes to overcome the problem of feeding and unloading the workpieces to and from the vertical lathes, whether the latter be used individually or in groups operating in a cascade arrangement, by means of a solution which is more simple and economical than the current solutions and which is based on the following observation.
  • the tool-carrying slide or slides or the so-called cross slides of the lathe are normally connected to the fixed supporting structure of the lathe itself, with the possibility of performing displacements in both the horizontal and vertical direction.
  • the idea has been conceived to dimension these displacements such that the lathe is able to load and unload automatically the workpieces, simply by providing manipulators directly on-board the said tool-carrying or cross slides.
  • the tool-carrying or cross slide positions the manipulator which grips and removes the workpiece itself from the chuck and then unloads it, while simultaneously or subsequently, another manipulator mounted on the same slide or on another tool-carrying or cross slide of the same lathe grips a new workpiece to be machined and positions it on the chuck.
  • FIGS. 1, 2 and 3 are front and schematic views of a tool-carrying or cross slide of a vertical lathe provided with manipulators and shown, respectively, during certain stages of machining of a workpiece and during unloading and feeding of the workpiece itself from and to the chuck.
  • S denotes the slide which in the example in question carries four tool stations U1, U2, U3 and U4 and which, by means of guides and slides of the known type, not shown, is able to perform precise displacements which are of significant amplitude also, in both the horizontal and vertical direction, as indicated by the arrows F1-F2.
  • the tool stations are progressively used for machining the workpiece P located on the carousel or chuck G with a vertical axis.
  • the possibility of horizontal displacement of the slide S is adapted, in terms of amplitude, to the new requirements and, if necessary, the means which control the horizontal displacements of the slide itself are programmed so as to perform also rapid approach movements.
  • manipulators M1, M2, or grippers On the opposite sides of the slide S there are mounted respective manipulators M1, M2, or grippers, able to grip one of the workpieces P to be machined and able to operate automatically in the manner described below.
  • the lathe On the opposite sides of the lathe are arranged two conveyors T1, T2 equipped with means for supporting the workpieces P and able to perform precise movements such that the supporting means are precisely positioned in the stations S1 and S2 which have a precise spatial location and are located at the same distance from the axis of the chuck G. This distance is the same as the mutual distance between the manipulators M1, M2.
  • the slide S continues its displacement to the left and arranges the manipulator M2 on the machined workpiece, while the manipulator M1 is in the station S1.
  • the manipulator M2 grips and extracts the machined workpiece from the chuck G, while the manipulator M1 grips and raises the workpiece P to be machined from the station S1, as shown in continuous lines in FIG. 3.
  • manipulators M1 and M2 may be produced in any suitable manner, for example also so as to modify the orientation of the workpiece during loading and/or unloading.
  • the manipulators may be mounted on the slide or slides S with the possibility of performing on the latter independent and precise displacements on one or on several axes.
  • the manipulator Ml will be mounted on one slide and the manipulator M2 will be mounted on another slide.
